It's inertia. A rule that you see every day, for example a brick will stay in the same spot unless a force acts on it.
The answer is a property of density. The higher the density, the higher the pressure at the bottom.
Pressure = mass / Area. So given that the 4 samples occupy the same area at the bottom, the mass is going to be the determining factor. Per given volume, mercury has the largest mass. The answer is A
Explanation:
the force acting perpendicularly on unit area of surface
- unit=pascle .
<em>The </em><em>nucleus</em><em> has most of the atomic mass in an atom. The </em><em>nucleus</em><em> is made up of protons and neutrons.</em>
